My invention relates to a brake hanger bracket for a railway car and more particularly to a novel arrangement of such a bracket designed to eliminate play between the parts including the hanger associated therewith, thus greatly reducing the wear.

It is well known that the major portion of the wear in a brake hanger and in the bracket from which it is supported is generally due to the vibration which develops between the parts. The necessary manufacturing tolerances which enable the parts to be fitted together originally requires a certain amount of play between the parts and this develops rapidly under service conditions. Numerous forms of wear plates have been devised in order that wearon the brake hanger bracket may be prevented, said wear plates commonly being renewable from time to time as necessary. Eifort has also been made to provide against vibration such as above mentioned by means of the use of the springs designed to prevent vibratory movement between the parts.

I have devised a simple method of securing the parts which confines the wear to the engaging surfaces between the brake hanger and the wear plate itself and thus reduces to a minimum the wear occurring on such a structure.

The attached drawing shows embodiments of my invention wherein Figure l is a fragmentary side elevation of a truck structure incorporating my novel brake hanger bracket; Figure 2 is a top' plan view thereof; and Figure 3 is a sectional view taken through the structure shown in Figures 1 and 2 and substantially as indicated by 35 the line 3-3 of Figure 1, the wear pad being shown in bottom plan;

Figure 4 shows a further modification of my invention, the view being a side elevation corresponding generally to the view shown in Figure 1.

Describing more particularly the embodiment shown in Figures 1 to 3, the truck frame member 2 has the integrally formed brake hanger bracket 4, the juncture of the bracket with said member being reinforced by the substantially vertically arranged rib 6 which merges with the said memher 2 and the top wall of the bracket. The bracket terminates in a jaw-like structure having the flaring top and bottom walls 8 and I0 and the integrally formed lateral walls 12 and I4, said 50 lateral walls having front edges of arcuate form as indicated at It, thus accommodating my novel form of two-piece wear plate comprising the top member i8 and the bottom member 20 abutting each other along the plane indicated at 22 (Figure 1). At the rear of said wear plate is formed Chicago, 111., a corpora- 1938, Serial No. 237,604

the opening 24 receiving the top member 26 of the loop-type hanger 28, the said top member being seated upon the lower portion 20 of the wear plate and having a snug fit as at 30 with the top portion l8 thereof. The bottom portion 20 of the wear plate has the guide flanges 32, 32 seating against the lateral edges of the bottom wall It of the jaw structure, thus serving as additional positioning means. Upon the bottom surface of said member 20 are secured the rubber pads 34, 34, said rubber pads being secured as at 36, 36 to said member 20 by means of lugs formed on said pads and forced into openings in the bottom wall of said member 20, said openings beingof the form best seen at 38, 38 (Figure l) with relatively small orifices, thus securing said pads in position on said wear plate member 20 after the lugs are forced through said orifices. Aligned openings are formed in the top and bottom walls 8 and ll] of the jaw structure and the upper and lower portions l8 and 20 of the wear plate are slotted for the reception of the securing bolt 4|], said securing bolt being retained in position after assembly by the threaded nuts 42, 42.

In assembly the top and bottom portions of the wear plate may be positioned upon the top member of the hanger and thereafter forced into the jaw opening until the slots of the wear plate are aligned with the openings in the top and bottom walls of the jaw structure, thus permitting the retaining bolt to be mounted in position. In this operation the rubber pads 34, 34 will be compressed and after the securing bolt is in position will tend to expand, thus holding the parts in tight engagement with each other.

The modification shown in Figure 4 is generally similar to that in the modification just described as far as concerns the frame member 2, the bracket 4, the reinforcing rib 6 and the jaw structure with the flaring top and bottom walls 8 and I0 and the lateral walls l2 and I4 terminating in arcuate front edges It also in the form of the hanger 23 in the top member 26 thereof. The embodiment shown in Figure 4, however, differs from that previously described in the form of the wear plate generaly indicated at 44 and comprising the top portion 45 and the bottom portion 48. Said top and bottom portions are generally similar in form to the top and bottom portions of the wear plate previously described except that each is provided with a pair of rubber pads as indicated at 5!) for the top portion and 52 for the bottom portion of said wear plate. Said rubber pads are secured as at 54, 54 in the manner described for the previous embodiment, but said top and bottom portions engage each other only as indicated at 56, being relieved as indicated at 5B and spaced apart at their rear ends as at 60 so that the top member 26 of the brake hanger 28 will be clamped therebetween with some slight compressive force as the rubber pads 50 and 52 are compressed in the operation of assembly which is substantially similar to that previously described with the same form of securing bolt 40. In this embodiment it will be apparent that I have provided an arrangement which will afford some resilience between the wear plate and the brake hanger jaw and so accommodate slight movements of the brake hanger between the parts of said wear plate, said parts, however, being so arranged as to exert some slight compressive force against the top member, thereby preventing any chattering between the said parts and said hanger. In this arrangement also it will be apparent that no wear will occur between the parts of the wear plate and the walls of the brake hanger jaw inasmuch as the engagement between these parts is through the before mentioned rubber pads.

It is to be understood that I do not wish to be limited by the exact embodiments of the device shown which are merely by way of illustration and not limitation as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
